About this replacement
ELCA CONTROL-GEH-A / TECHNO-M Series — 7.2V Ni-MH Replacement Battery (PINC-GEH)
This is a 7.2V 1200mAh Ni-MH replacement battery for ELCA wireless crane remote controls. It fits the CONTROL-GEH-A, CONTROL-GEH-D, TECHNO-M, SFERA GENIO, and eight additional ELCA remote models. OEM part numbers PINC-GEH, 0401BA000109, 0401BA000113, and 04.142 all cross to this cell pack.
- CONTROL-GEH and TECHNO-M series compatibility: These remotes share the same 7.2V six-cell Ni-MH architecture, identical connector pinout, and matching BMS handshake protocol — which is why one cell pack covers the full range. Voltage tolerance across the series is tight, and Ni-MH holds that rail steady under the brief inrush spikes from solenoid and relay actuation.
- Bench tested on actual hardware: We cycled this pack through full charge and discharge on ELCA remote hardware and confirmed the BMS accepted the cell chemistry without fault codes. Solenoid activation during testing did not cause voltage dropout at this capacity rating.
- Storage charge for infrequently used remotes: If this remote sits unused in a cabinet between jobs, charge the battery once a month. Ni-MH self-discharges at roughly 1–2% per day at room temperature. A pack left for several months can drop low enough that the charger fails to detect a valid cell — a 30-minute charge first will recover it in most cases.
Solenoid activation causing power dropout on a freshly installed battery
When an ELCA remote triggers a crane solenoid or contactor, the inrush current draw spikes sharply for a few milliseconds. A partially depleted or heavily aged cell pack can sag below the BMS cutoff threshold during that spike, causing the remote to reset or cut out at the moment of activation. This pack is rated at 1200mAh, which keeps the internal impedance low enough to handle normal solenoid inrush without dropout. If cutouts persist after fitting a fresh cell, check that the battery is fully charged — a Ni-MH pack at storage voltage (around 7.2V open circuit) has not yet reached working capacity.
Remote shows low-battery indicator immediately after new cell install
Ni-MH cells ship in a partial storage state, typically sitting between 6.8V and 7.2V open circuit. The ELCA remote reads this as a depleted pack and flags low battery before the first use. This is not a fault with the battery. Put the pack on the ELCA charger for a full cycle before operating the remote — a fully charged 7.2V Ni-MH pack measures approximately 8.4–8.6V at the terminals. Once charged, the low-battery warning should clear on power-up.
